摘要：Energy storage has garnered global attention as a promising solution to the intermittent nature of renewable energy sources. For large-scale (>100 MW) energy storage technology, there are only three types: Pumped Hydroelectric energy storage (PHES), Compressed air energy storage (CAES) and Liquid air energy storage (LAES). The limitation of PHES is that several natural geological features are needed. The traditional CAES needs a combustion chamber, which will result in environmental problems. LAES offers several advantages over traditional CAES systems, including higher energy density, scalability, flexibility in site selection, lower environmental impact, cost-effectiveness, and compatibility with renewable energy sources. Under these conditions, LAES is more suitable than other systems. This investigation examined a novel zero-carbon system integrating LAES with CBC and solar power. The primary objective is to maximize the round-trip efficiency (RTE) of the system while simultaneously minimizing the total investment cost per unit of output power (ICPP). By systematically exploring the trade-offs between RTE and ICPP, the study seeks to identify the proposed system's most efficient and economically viable configurations. Each subsystem was simulated using Aspen Plus (R) V12 and validated against actual plant data. The analysis indicates that the proposed optimal LAES-CBC system could achieve a remarkable increase in RTE up to 67.81 %, representing an increase of 11.18 % compared to the baseline. Additionally, the total ICPP could be reduced to 0.2739 $/kWh, marking a decrease of 5.96 %. The charging process of the LAES system emerges as a critical focal point due to its significant contributions to exergy destruction and equipment costs. This study provides valuable insights into enhancing and achieving maximum efficiency and cost-effectiveness. These insights are essential for accelerating the transition towards a carbon-neutral energy system, highlighting the importance of research in advancing sustainable energy technologies.
